Ex-Manchester United star David May admitted he is worried about what would happen to his family if he developed . May, 54, spent most of his career turning out for and , while also having stints at and

The former central defender played at the highest level for around 18 years. Across that time, he estimates that he would have headed the ball around 20,000 times, having played in an era where the ball was kicked in the air more often and the footballs themselves were heavier.

In May, took steps to address worries about the dangers of heading by introducing a new rule aimed at phasing out the deliberate heading of a ball in youth football. The ex-United player opened up about his dementia fears in a revealing interview on BBC Breakfast, where he was also accompanied by John Stiles, the son of England 1966 World Cup winner Nobby,

May told BBC Breakfast: "I didn't know anything, it's only really coming to light now that this [dementia fears] is coming out. Would I have the care from the governing bodies, from the PFA, the funding, that these families now, are not actually getting?

"It's worrying. Yeah, I'm worried, of course I am. I've got a family to look after. I don't want my children looking after me day in and day out."

Stiles offered an insight into the heartbreaking final years of his famous father Nobby. As well as the emotional heartbreak of watching their father's suffering, they also struggled with the high cost of care.

Stiles said: "Care does cost a lot of money and the money that's going into the PFA, is it enough money to care for the future generations, who one in three have a possibility of getting dementia?"

After his passing at the age of 78, the Stiles family donated the World Cup winner's brain to Dr. Willie Stewart, who revealed that Nobby was free from vascular dementia and Alzheimers, but suffered from something else that was believed to be caused by heading footballs.

Stiles added: "The disease that killed him is called chronic traumatic encephalopathy (CTE). I asked him (Dr Willie Stewart) how many footballers brains he examined had CTE, it was 70%. That's what killed my father.

"If my dad didn't have medals to sell, I don't know what my family would've done. That is what is happening with families now. Football families, when they go into care homes, they're in a terrible state.

"That is why we're campaigning to get help for those families, who basically are in a complete financial mess when their loved one goes into a care home."
